Title:
QUANTUM-DOT DIFFUSION PLATE, AND PREPARATION METHOD THEREFOR AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/160107
Kind Code:
A1
Abstract:
The present invention belongs to the technical field of quantum-dot diffusion plates, and particularly relates to a quantum-dot diffusion plate, and a preparation method therefor and the application thereof. The quantum-dot diffusion plate comprises a diffusion layer, a quantum dot layer and a transparent layer, wherein the quantum dot layer is arranged between the diffusion layer and the transparent layer. The design of the diffusion layer and the transparent layer, which are respectively at the upper portion and lower portion, can ensure that quantum dots are protected by the upper and lower layers as well as ensuring a lighting effect of the diffusion plate, thereby preventing the quantum dots from inactivation caused by the impact of external factors during the use and storage of the quantum dots, and improving the brightness retention rate. Moreover, the upper, intermediate and lower layers in the present invention are made of the same base material, and the linear expansion coefficients of the three layers are consistent, thereby effectively avoiding the problem of image distortion caused by the differences between different inter-layer sizes caused by a change in the environmental temperature during the use and storage processes.
